テスラとフォルクスワーゲンを比較し、ESG格付の不一致が資金制約を強める仕組みを情報非対称性・ステークホルダー理論・シグナリング理論から分析。格付差による資金調達難の要因を「情報の曖昧さとリスクプレミアム」「ステークホルダー交渉」「シグナルの信頼性分化」の3点に整理し、ESGシグナルの一貫性が低いほど制約が深刻化すると論じる。企業にはESG活動のバランスと開示改善を、政府には標準化された協調的ESG格付制度の構築を提言。
English
Comparing Tesla and Volkswagen, this paper analyzes how ESG rating divergence intensifies corporate financing constraints through information asymmetry, stakeholder theory, and signaling theory. It identifies three channels—information ambiguity/risk premium, stakeholder bargaining, and signal credibility differentiation—and argues that inconsistent ESG signals raise financing costs. It recommends firms balance ESG activities and improve disclosure, and governments build standardized, cooperative ESG rating systems.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準の導入や有報でのサステナビリティ開示義務化が進む日本では、格付機関間の評価不一致が投資家の意思決定や調達コストに与える影響が実務課題となっている。本稿の情報非対称性フレームは、日本企業が統合報告書や対話でESGシグナルの一貫性をどう確保すべきかを考える上で示唆を与える。
In the global GX context
As ISSB/CSRD disclosure regimes expand, ESG rating divergence is a recognized obstacle to comparability and capital allocation. This paper's signaling/information-asymmetry framing helps explain why inconsistent ESG signals raise financing costs, complementing global work on rating agency methodology and disclosure standardization.

📄 Abstract（原文）
Based on the problem of information asymmetry and the theories of stakeholders and signalling, Tesla and the Volkswagen Group are selected as comparison cases in this paper to explore how different ESG ratings affect the financing constraints of enterprises. Based on the research, the three reasons for financing difficulty due to rating differences are “information ambiguity-risk premium”, “stakeholder bargaining” and “signal credibility differentiation”, and the severity of the constraint is negatively correlated with the consistency of ESG signals. Tesla has had a somewhat declining ESG score over time and is therefore more exposed to investment risk, credit risk and others. Volkswagen has been making systematic reforms after the scandal and is now carrying out good ESG management and open disclosures to reduce the rating drop and secure funds. As shown in the above results, the inconsistency of signals has increased information asymmetry and reduced the efficiency of signaling; thus, it has raised financing costs. Consistently signalling will lower these constraints. Therefore, this paper puts forward that enterprises should increase the balance of ESG activities and improve information disclosure; at the same time, the government can reduce financing friction by establishing a standardised, cooperative ESG rating system. This paper presents some problems at the micro level related to the economic impact of ESG rating discrepancies.
